@zacharylouiskane@gmail.com, happy to help!I believe your question refers to Example #4 from the video, not Example #5.
The word "substantiate" means "prove" and the word "assertion" means "statement." So, we can think of the phrase "appealing to authority to substantiate an assertion" as the same as "appealing to authority to prove a statement."
Try not to get thrown off by flowery wording. We know that this answer choice is correct regardless of what the second part of the sentence says. This is because there is no appeal to authority, so the reason behind the appeal (to prove a statement) is meant for descriptive purposes and would be irrelevant.
Does that make sense? Hope it helps! Please let us know if you have any other questions!
